It is possible to mute posts and accounts within communities, but why? gu.cards is legit.

afaik gu.cards has been out of date for a while now
idk how the tournament tickets were distributed before, you should ask older players

Do you have any more info on why you think it's a scam?

i wasn't online, we're opposite timezones.
the tickets were already distributed, this site is either just a remnant of the old distribution website, or is a phishing attempt from someone, with crypto it's always best to be safe than sorry. And considering tickets were already distributed, the site either does absolutely nothing and you pay gas fees for nothing, or is phishing for an allowance smart contract, both outcomes aren't good.

After some research, you were right. All tickets have been sold out so don't interact with this website.

Muted the post.
